Traveling cross country through stream beds, navigating around downed trees and brush, and grooming up steep grades can sometimes require additional traction. Tucker Sno-Cat® vehicles offer ARB Air Locker differentials as an option. Depending on the situation, the operator simply actuates the on-board air compressor, and selects the rear locker or both front and rear. This positively locks the differentials and offers maximum traction. ARB Air Locker differentials have proven to be tough and reliable in the winter’s harsh conditions.
